Mike Zimmer keeps it real on how he'll handle Cowboys defense

After losing Dan Quinn to the coaching carousel, the Dallas Cowboys hope that Mike Zimmer can step in and keep their defense strong. Zimmer spent seven seasons in the early-to-mid 2000s serving as the Cowboys defensive coordinator after six seasons as a defensive assistant, spending most of his time with the secondary. With Dallas eager to finally make a deep playoff run, Zimmer has to step up and do his part.
